World class surveillance radar

Terma’s surveillance radar, Scanter 4100, is built with the absolutely latest technology and is able to meet or exceed the most stringent requirements for performance and cost efficiency.

Both the British and the Danish navy have chosen to install the model on their vessels with the motivation: 

– If there is something out there, we must be able to see it – under all circumstances! 

That requirement applies to movement and crafts, both in the air and on the surface of the water. One of the major difficulties was to design radar with the highest possible performance at a sufficiently low price to allow authorities to equip a large number of vessels within the constraints of their appropriations. 

Scanter 4100 operates with two radar beams – one for the air space and one for the sea surface – transmitted and received via a common parabolic reflector antenna. The unique aspect of Scanter 4100 lies in the combination of a common transmitter with two independent receivers of radar pulses using optimised signal processing and tracking techniques for the respective air and surface channels.

Terma has delivered a complete radar installation type Scanter 4100 in the new Danish patrol vessel Knud Rasmussen. The vessel is of type “Artic Inspection Vessel” with the task of guarding Denmark’s arctic territorial waters. It is easy to understand how important the radar installation is to fulfil that task.

– We have sailed the waters around Greenland with extensive tests of the new vessel, including the radar, says Terma’s project manager Egon Laursen, and continues:

– This environment puts all technology to the test and it is our responsibility to make sure that Scanter 4100 is up to the challenge. We have ensured that the crew of Knud Rasmussen is able to maintain full surveillance at all times and under all circumstances.

ISIC has delivered three robust marine PCs for this system, two of which run the function of tracking targets in the air space and on the surface of the sea. The third unit is used for the radar’s support functions and systems monitoring. 

Terma is a Danish company that develops complicated technical systems and products for customers in the aerospace and aircraft industry, and for the marine industry. Terma’s products are built to stand up to the most extreme strains encountered at sea because of weather, wind, cold, rain and snow. They are built to function without disruption in situations where human life and huge economic values are at play.

ISIC is a leading manufacturer of computers and monitors for industrial, marine and military use. ISIC develops and markets hardware that can withstand demanding environments and extreme vibration, extreme temperatures, moisture and vibrations. The units are designed and certified in accordance with international standards. ISIC is a part of division Electronics in Lagercrantz Group.
